Smile Lasik is the newest version of laser vision correction. Smile treatment consists of one painless laser step lasting 33 seconds. You are able to get up and see immediately, though the final vision, as with all laser vision correction techniques, takes about three months to finalize.
Smile Lasik has some advantages and disadvantages compared to traditional Lasik.
There is no flap with Smile Lasik. The treatment is performed completely within the interior of the cornea, so there is no flap at all. Patients do not have to worry about a flap that can be moved or disturbed in the future. You therefore do not need to use goggles to protect your eyes during the initial few days after Smile Lasik.
There is less dryness with Smile Lasik. Because there is no flap, fewer of the corneal nerves are affected, leading to less dryness. You therefore do not need to use moisturizing drops very much after Smile Lasik.
For higher corrections, Smile Lasik is more accurate. Therefore, for higher corrections, the need for a touch-up or enhancement is less likely.
Smile Lasik has slightly less sharp vision than Lasik during the first week or two. 20/30 vision is common on the first day, gradually improving to 20/20 over the first week or two. This visual recovery is slower than Lasik, which typically produces 20/20 vision the next day, but faster than PRK. Full vision recovery, as with all forms of laser vision correction, takes about three months.
Enhancement of Smile Lasik cannot be performed with Smile Lasik, but must be performed with the slower healing PRK laser treatment. Enhancements (fine-tuning procedures) are performed in 4% of patients.
